Abstract: An electrolyte for an aluminum electrolysis capacitor and the aluminum electrolysis capacitor using the electrolyte are provided. The electrolyte comprises a primary solute, a primary solvent, and an additive as shown in a structural formula 1, wherein, R1 and R2 are each independently selected from —CH3, —CH2CH3 or —OH; R3 and R4 are each in selected from —(CH2CH2O)mH or —H, and n and m are integrals ranging from 1 to 10000, respectively. The electrolyte has excellent anti-corrosive performance and is capable of maintaining long load service life under the condition of relatively high chlorine ion content, and there is no evidence of corrosion in the capacitor after it is disassembled.
